Abstract:
According to the authors the research could prove to be of great importance for the future development of quantum computation. The experiment illustrates the transition between the quantum and the macroscopic worlds. Conclusions appear in the latest issue of Science.

An international investigation involving the participation of the Consejo Superior de Investigaciones Científicas (CSIC) has reproduced the experiment of Thomas Young in a molecule of hydrogen, the smallest molecular system that exists. In 1803 the English scientist tested a pattern of interferences in light from a distant source, on passing through a "double slit" and thus being refracted. This finding confirmed the theory that light had wave motion properties. The authors of this current research, which appears in the latest issue of the journal Science, uses electrons instead of light and the nuclei of the hydrogen molecule as emitting slits.
